Worst Service I have ever experienced

I got a tablet from Sell Direct in April, it didnt work. It was a struggle to ven return it to them. After going up and down between Telkom Mobile in Sandton and Sell Direct call centre, it was finally taken back.<br> I was promised it would take 12 days to repair and I would get a response. It has been a month now,I have never heard from them again. I called them today the 22nd of May, they still working on it. I asked, i dont have the devise but yet i liable to pay the first contract fee this month. They could not anwer me, promised to call me back with feedback. I decided to call them back again. Since 10:30 there is no response from the call centre.<br> How can i be liable to pay for a devise that I have never used and do not have it in possesion, their repsonse is, 'ive got the sim card activated. Doesnt a sim card need a phone to work. The time i get through to them, the whole contract must be cancelled. They are just so bad in everything. If they anwer the phones, im not hopefull.
